If you're interested in learning about aquaponics and have a pond, Arturo may have an offer for you. He is interested in researching floating islands for use in aquaponics, or would that be 'aquapondics'?
Contact Arturo at aquaponicaustin.com to inquire. I believe he's up north 183 and would be a better situation if you were also north. Let him know if you're interested in this experiment.
I'll update if this is incorrect.
